With this latest GitSense iteration for Bitbucket Server, Bitbucket users can now perform always relevant code searches, which is something you can't do in GitHub Enterprise or GitLab EE. It also introduces what I believe to be a first of its kind, which is a code search tree. With this tree, you can drill into your code search results, by traversing a tree, which can come in handy for situations where you have 100s of matches.
